Abstract
L'invention concerne un procédé amélioré de prédiction de vecteur de mouvement temporel pour un HEVC interbloc qui repose sur un modèle de translation de bloc. Le procédé ajoute un décalage à un prédicteur de vecteur de mouvement temporel (TMVP, "temporal motion vector predictor") pour améliorer la précision de prédiction. Le procédé désigne tout d'abord un bloc de prédiction actuel en tant que zone de compensation de mouvement, tous les pixels à l'intérieur du bloc de prédiction effectuant une translation identique dans le temps à l'aide de vecteurs de mouvement (MV, "motion vector"). Un décalage de coordonnées est ensuite calculé pour un bloc de prédiction actuel à partir des MV de ses blocs spatialement voisins. Le TMVP à décalage est ensuite défini pour le bloc de prédiction actuel en tant que MV d'un bloc de décalage qui est dans l'emplacement géométrique des coordonnées de bloc de prédiction actuel, auxquelles s'ajoute le décalage de coordonnées, dans une image de référence temporelle spécifiée. Le décalage TMVP est ensuite utilisé pour coder des MV.
